Installing and Configuring the 82350 1
82350B Installation and Configuration Guide 31
Example: GPIB Interface Configuration
An I/O interface consists of a hardware interface
and a software interface. One purpose of the
Connection Expert utility is to associate a unique
software interface ID with a hardware interface.
The Agilent IO Libraries Suite uses an Interface
ID or Logical Unit Number to identify an
interface. This information is passed in the
parameter string of the viOpen function call in a
VISA program or in the iopen function call in a
SICL program.
For example, the GPIB interface system in
Figure 1-13 consists of a Windows PC with two
82350 GPIB cards connected to three GPIB
instruments via GPIB cables. For this system, the
Connection Expert utility has been used to assign
GPIB card #1 a VISA interface ID of “GPIB0” and a
SICL interface ID of “gpib0”.
Connection Expert has also been used to assign
GPIB card #2 a VISA interface ID of “GPIB1” and a
SICL interface ID of “gpib1”. With these names
assigned to the interfaces, the VISA/SICL
addressing is as shown in the figure. Since unique
names have been assigned by Connection Expert,
you can use the VISA viOpen command to open
the I/O paths to the GPIB instruments. Or, you can
use the SICL iopen command to open the I/O
paths shown.
